Hello Sandra.Which makes more sense? Installing the Midnite Solar Surge protector at the Flexmax charge controller or at the ICS Plus Combiner?I will be installing a system with 6 Flexmax 80 charge controllers for 6 arrays with 5 strings each and three 8048 Radians each with their own GSLC.There will be 6 ICS combiners and an RSI.I will also be using a Midnite Solar battery combiner underneath the 3 GSLC's.There will be a 48 volt 3060 amp-hours Absolyte AGB battery bank.All the components have been ordered through AEE and will ship this week (the 90 solar panels have arrived this week at the client site).Installation is schedule for the week of 11-16 Sept 2017.This will be an off-grid system with NO grid power.-Art.

Hello Sandra.For my project I have a ICSPlus-4 and 2 more combiners for a total of 6 combiners.Does a single power supply energize 6 combiners and the RSI?Does the power supply go into the GSLC for the Master Radian or can the power supply go into the GSLC for a slave Radian? -Art.
